Disclosed is a consumer product comprising a plurality of microcapsules dispersed in a dispersing medium. The microcapsules comprise a core and a shell around the core. The core comprises at least one functional material. The shells of the microcapsules are coated with chitosan. The dispersing medium comprises additional free chitosan. Disclosed is also a method for making such a consumer product, a method for enhancing the deposition and rinse resistance of a plurality of microcapsules dispersed in a dispersing medium and a use of chitosan for enhancing the deposition and rinse resistance of a plurality of microcapsules dispersed in a dispersing medium. L'invention concerne un produit de consommation comprenant une pluralité de microcapsules dispersées dans un milieu de dispersion. Les microcapsules comprennent un noyau et une enveloppe autour du noyau. Le noyau comprend au moins un matériau fonctionnel. Les enveloppes des microcapsules sont revêtues de chitosane. Le milieu de dispersion comprend du chitosane libre supplémentaire. L'invention concerne également un procédé permettant de fabriquer un tel produit de consommation, un procédé permettant d'améliorer le dépôt et la résistance au rinçage d'une pluralité de microcapsules dispersées dans un milieu de dispersion et une utilisation de chitosane permettant d'améliorer le dépôt et la résistance au rinçage d'une pluralité de microcapsules dispersées dans un milieu de dispersion.
